9514 1404 393
Answer:
153 square units
Step-by-step explanation:
The figure is drawn in the attachment with some lengths and points labeled.
The figure can be considered to have an area that is the sum of the areas of rectangle ABFE and triangle FGH, with the area of triangle BCD subtracted.
That area is ...
A = area(ABFE) +area(FGH) -area(BCD)
= (15)(9) +(1/2)(9)(6) -(1/2)(6)(3)
= 135 +27 -9 = 153 . . . square units
Simplify: 16 - [11 - {8+ (17 +3x2 - 19)}]
The given expression
= 16 - [11 - {8+ (17 + 3 x 2 - 19)}]
= 16 - [11 - {8+ (17 + 6-19)
= 16 - [11 - {8+ 4)] = 16 -- [11 -2]
= 16 - 9 = 7.

Por favor cómo se resuelve esta matriz por método Gauss-Jordan
Responder:
la solución (x, y, z) es (4.48, 4.86, -1.04)
Explicación paso a paso:
Dadas las ecuaciones simultáneas;
6X + 8Y - 4Z = 5 .... 1
1X + 2Y + 5Z = 9 ... 2
9X - 3Y + 3Z = 6 .... 3
Primero necesitamos reducir el sistema de ecuaciones
Ecuación 1 * 1
Ecuación 2 * 4
__________
6X + 8Y - 4Z = 5
4X + 8Y + 20Z = 36
Restar
6x-4x - 4z-20z = 5-36
2x-24z = 31 ... 4
también
ecuación 2 * 3
ecuación 3 * 2
_______________
1X + 2Y + 5Z = 9 * 3
9X - 3Y + 3Z = 6 * 2
_______________
3x + 6y + 15z = 27
18x - 6 años + 6z = 12
Agregar
3x + 18x + 15z + 6z = 27 + 12
21x + 21z = 39 ...... 5
Resolviendo 4 y 5
2x-24z = 31 ... 4 * 21
21x + 21z = 39 ...... 5 * 2
____________
42x - 504z = 651
42x + 42z = 78
Sustraer
-504x - 42z = 651-78
-546z = 573
z = -573/546
z = -1.05
Sustituye z = -1.05 en 4
De 4;
2x-21z = 31
2x - 21 (-1,05) = 31
2x + 22,04 = 31
2x = 31-22.04
2x = 8,96
x = 8,96 / 2
x = 4,48
Obtener y
De 2:
X + 2Y + 5Z = 9
4.48 + 2y + 5 (-1.04) = 9
2 años + 4,48-5,2 = 9
2y = 9 + 0,72
2 años = 9,72
y = 9,72 / 2
y = 4,86
Por tanto, la solución (x, y, z) es (4.48, 4.86, -1.04)
The figures are similar. Find x.
Which expression is equivalent to 9/8
eight less than the product of a number n and 1/5 is no more than 98
Answer:
8<n+1/5<98
Step-by-step explanation:
2x plus 3 plus x2; for x = 4
Answer:
2x+3+x2 if x=4 is 27
Step-by-step explanation:
2*x or 2*4=8
8+3=11;
and x or 4 times itself is 16
so we add it all together and get 27.
Have a great day!
Answer:
27
Step-by-step explanation:
Not sure if you mean x to the power of 2, so I'll assume that.
Replacing the variable for 4 should look like:
2(4) + 3 + 4^2
8 + 3 + 16 (4 to the power of 2 is equivalent to 4 x 4 which is 16)
Now add them all, 27.

Maribel is packing boxes of canned goods for the food drive. Each box can hold 8 books. How many boxes are needed for 122 books?
answer is:16 books
Answer:
16 boxes will be needed for 122 books.
Step-by-step explanation:
Given that,
Each box can hold 8 books.
We need to find the number of boxes needed for 122 books. It can be calculated as follows :
[tex]\dfrac{122}{8}[/tex] = 15.25
It means 15 boxes can be filled and 16 boxes will be needed for 122 books.

[tex]2x - 10 = x + 6 \\ 2x - x = 6 + 10 \\ x = 16[/tex]
[tex]let \: (y) \: the \: angle \: which \: wanted \\ 90 = y + (2x - 10) \\ 90 = y + (32 - 10) \\ y = 90 - 22 \\ y = 68[/tex]

Robert is serving 16 drinks to his friends. Three times as many friends are drinking lemonade as tea, and 4 are drinking water. How many of each type of drink does Robert serve?
Answer:
9 lemonade, 3 tea, 4 water
Answer: Robert should serve 3 for tea, 9 for lemonade, and 4 for water.
Step-by-step explanation:
Since you don't know how many friends are drinking lemonade or tea, you should give them variables.
x = amount of friends drinking tea
3x = amount of friends drinking lemonade
We already know how many are drinking water, so there's no need for a variable.
Then, make an equation:
x + 3x + 4 = 16
Simplify:
4x + 4 = 16
Isolate the variable by subtracting 4 from both sides:
4x = 12
Isolate the variable by dividing both sides by 4:
x = 3, so 3 friends are drinking tea
3x = 9, so 9 friends are drinking lemonade
Double check the work by replacing the variables with their actual numbers:
3 + 9 + 4 = 16
Simplify:
16 = 16
Therefore, the answer is correct.

What is 3(2x +7x - 5 )
Answer:
x = 15/27
Step-by-step explanation:
3(2x + 7x - 5)
Distribute the 3
6x + 21x - 15
Combine like terms
27x - 15 = 0
27x = 15
x = 15/27
Answer:
27x - 15 is your expression
Step-by-step explanation:
3 x 2x = 6x and 3 x 7x = 21x so 21x + 6x = 27x and 3 x 5 = 15 so 27x - 15 is your expression

2. There are 12 high schools competing in a basketball tournament. In how many ways can the teams be placed
(1º, 2nd, .., 12th) at the end of the tournament?
Answer:
The teams can be placed in 479,001,600 ways.
Step-by-step explanation:
To solve this question, we want to know in how many ways 12 elements can be arranged.
Number of possible arrangements of x elements:
The number of possible arrangments of x elements is given by:
[tex]A_{x} = x![/tex]
In this question:
12 teams, so arrangment of 12 elements.
[tex]A_{12} = 12! = 479001600[/tex]
The teams can be placed in 479,001,600 ways.
